This letter is in response to your request to open an investigation regarding the alleged deposit of deleterious substances in the St. Lawrence River. According to your April 11th, 2002 request, these substances would come from the Technoparc site in Montreal. As indicated in our letter sent to you on April 22nd, Environment Canada opened an investigation relatively to the general prohibition concerning the deposit of a deleterious substance in water frequented by fish as prescribed under section 36(3) of the Fisheries Act.

We have investigated the historical facts of the Technoparc site, the origin and type of the contamination and the geology of the site. The analysis that we have done does not allow us to determine the precise source of the deleterious substances released to St. Lawrence River. Therefore, Environment Canada brings closure to the investigation that you requested on April 11th, 2002.

Please be assured that Environment Canada is continuing its efforts with different stakeholders to find a sustainable solution to protect the environment.

We thank you for your interest in the protection of the St. Lawrence River.
